There are a few different ways that you can treat yourself with red light therapy. Some salons offer a tanning bed-style red light therapy machine, which looks very similar to a sunbed. However, the red light therapy beds do not release dangerous ultraviolet (UV) radiation as sunbeds do.
The most convenient way to treat yourself with red light therapy though is at home. Many kits can be bought for home use. Some kits are designed for use specifically on the face and come in the form of a facial mask, while others are hand-held devices that you hold onto your body, and others are larger screens that can treat larger areas such as the back or chest.
Another way that red light therapy can differ is the actual light used. Often nowadays, LEDs are used, but low-energy lasers can also be used. The light produced can vary between machines, with different wavelengths being emitted, such as infrared light. Different wavelengths can affect different symptoms differently, so it is good to find out which wavelength is best suited to treat your condition.
